Dugan Models E-1 and E-1A User Guide Chapter 1: Introduction The Model E-1A Automatic Mixing Controller helps professional audio engineers handle multiple live mics without continually riding individual faders. This multichannel audio signal processor patches into the channel insert points of a mixing console. The Model E-1 detects which mics are being used, and makes fast, transparent crossfades.
Dugan Models E-1 and E-1A User Guide When one person talks at a time, the Dugan Speech System rapidly fades that mic’s gain up and the others down. When the speaker pauses, that mic fades down and the others up, so the gain of all mics sums to equal that of one mic at full gain. When the next person talks, the system fades that mic’s gain up and the others down. The result sounds like passing one mic among several speakers. When multiple people talk at once, the gain is shared among active mics.

Dugan Models E-1 and E-1A User Guide Quickstart To execute a power-up Reset command, hold the channel 1 bypass button down during power-up. This sets all parameters to factory default settings and clears label text. We recommend executing a Reset command (just like “zeroing out” a console) before starting a new installation. Linking Multiple Dugans Up to eight Dugan units can be linked into a single automatic mixing system. One unit must be set to be the master and the others slaves.
Dugan Models E-1 and E-1A User Guide Figure 2-4 Setting console preamp gain 2. If there is insufficient gain to keep the level LEDs lit green when no one is talking, set the rear panel LEVEL switch to -10. The auto mix gain meters show the channel gains resulting from the process. They are not level meters! 3. Adjust your console’s preamp gains so all LED meters float at about the same gain when no one is talking. Each talker now has equal access to the system gain.
Dugan Models E-1 and E-1A User Guide Chapter 3: Installation and Configuration Installation We recommend placing the Model E-1A in a convenient place in the operator’s line of sight. A typical location is the center of the console’s meter bridge. Figure 3-1 Model E-1A placed conveniently Rack Mounting The Models E-1 and E-1A are each half-rack in width. They can be rack mounted as a single unit or as a pair side-by-side. Each unit ships with one long and one short rack ear and one joining plate.
Dugan Models E-1 and E-1A User Guide Power Supply Units shipped to the USA include a 12 V, 1.5 A, 120 VAC power supply. Contact the factory if you require a different power supply. In an emergency, the Model E-1A can accept power supplies within the following ranges: • 12–24 VDC, either polarity, 1.5 A • 9–18 VAC, 1.5 A Audio Wiring The ANALOG–DIGITAL switch selects which input is active, but both outputs remain active. Analog I/O Set the ANALOG–DIGITAL switch to ANALOG.
Dugan Models E-1 and E-1A User Guide Installation and Configuration Insert 1. Check the insert jack wiring on your mixing board. If they are 1/4-in TRS jacks (wired tip = send, ring = return), use TRS-TRS insert cables to connect the Model E-1A. Other configurations require special cables. The Model E-1A is wired as follows: tip = input, ring = output. 2. Patch the audio channels in the insert loop (send-return) of each console input strip.
Dugan Models E-1 and E-1A User Guide The Model E-1A has two digital operating modes: • 8 ch: Eight automxing channels, linking possible • 16 ch: Sixteen automixing channels, no linking The LINK IN and LINK OUT connectors are reassigned as audio I/O for channels 9–16. To set 16 ch mode, you can use the Dugan Control Panel (see Chapter 4: Dugan Control Panel), or a key command during startup (see Configuration on page 20).
Dugan Models E-1 and E-1A User Guide Installation and Configuration Signal Levels Analog The Model E-1A requires line level signals in the range -20 to +4 dBm; 0 dBm is optimal. The level LEDs light green for normal operation and red for overload. If there is insufficient gain to keep the level LEDs lit green when no one is talking, set the rear panel LEVEL switch to -10.
Dugan Models E-1 and E-1A User Guide Configuration Power-up Commands The Model E-1A can execute one of five commands during each power-up. Select the command by holding down a specific button during the entire power-up process, which takes just a few seconds. Power-up is complete after the LEDs stop flashing. To execute more than one command, turn the unit off after it finishes powering up, and repeat for the next command.

Dugan Models E-1 and E-1A User Guide Chapter 4: Dugan Control Panel The Dugan Control Panel has both Java and iPad versions. This chapter discusses the Java version and notes the iPad app’s few differences.
Dugan Models E-1 and E-1A User Guide Launch the Dugan-Control-Panel-vxxx.jar. If this file is not available and you have an Internet connection, you can obtain the latest version from: http://www.dandugan.com/downloads - OR http://tech.groups.yahoo.com/group/duganusers/files/ The Dugan Control Panel has three panes. The controls displayed in these panes depend on which Dugan device is selected in the Top Pane.
Dugan Models E-1 and E-1A User Guide Dugan Control Panel Setting Controls and Naming Units/Channels Setting Controls Controls can be adjusted five ways: • Enter a dB value in the numeric field. • Drag in the numeric field (not on iPad). When a slider is present: • Drag the slider up or down. • Click in the slider track to raise or lower the value by 0.5 dB. • Ctrl-click anywhere on the slider to reset its value to 0 (touch and hold on iPad).
Dugan Models E-1 and E-1A User Guide Channel Pane The Channel Pane contains the controls and indicators for each channel. Channels are always in one of three modes: man, auto, or mute. The active channel mode illuminates. All transitions are made with a smooth, rapid fade. Select a channel mode by pressing the individual mode buttons or the Master PRESET button. Figure 4-3 shows a typical system: channels 1–4 in auto with ambient noise, and channels 5–8 in mute.
Dugan Models E-1 and E-1A User Guide Dugan Control Panel Bypass When bypass is active, the signal passes through without automixing. That channel appears inactive, with all lights extinguished. Figure 4-4 bypass button lit Since all analog I/O is bypassed when the power is off, it is not necessary to unpatch the Model E-1A when not in use. If you are using analog I/O, bypass mode physically connects the input to the output with a relay. Channels are automatically bypassed when the power is off.
Dugan Models E-1 and E-1A User Guide Man In man mode there is no automixing, and the signal passes through at unity gain. Even though man and bypass modes perform similar functions, we recommend using man during live mixing to prevent clicks. Auto This is the normal Dugan automixing mode. Mute The channel is muted when mute is active. Preset Use the Preset function to store your favorite channel mode settings, which may be restored by pressing the Master PRESET button.
Dugan Models E-1 and E-1A User Guide Dugan Control Panel Channel Groups Each channel can be assigned to one group: a, b, or c. Each group functions as a separate, independent automatic mixer that can span multiple linked Dugans. Applications where groups are helpful include: • Separate Rooms: Assign the mics in each room to different groups so they function as separate automatic mixers.
Dugan Models E-1 and E-1A User Guide Meters The meters have three display modes. Meter Displays Meter Color auto mix gain action of the Dugan Speech System green input input level yellow output output level blue Table 4-1 Meter modes The default meter display is auto mix gain. This is the most useful choice during normal operation; the input and output meters are only used when setting or checking levels. Click on the Master meters button to toggle through the three meter display modes.
Dugan Models E-1 and E-1A User Guide Dugan Control Panel It is important to understand that the Speech System works by detecting the ratios of the levels between channels, not their absolute levels. The weight control is not a gate threshold! The following example explains how weight works (see Figure 4-9).
Dugan Models E-1 and E-1A User Guide Figure 4-10 shows eight- and four-mic systems with appropriate auto mix gain displays when no one is talking.
Dugan Models E-1 and E-1A User Guide Dugan Control Panel Master Pane The content of the Master Pane changes to reflect the Dugan device selected. This section documents the Model E-1A’s controls and indicators. The selected unit’s firmware and Control Panel (Java or iPad) versions are shown below the Dugan logo. Indicators Controls Figure 4-11 Analog (left) and digital (right) Master Panes Indicators The Master indicators include online, master/slave, analog/digital, and +4/-10.
Dugan Models E-1 and E-1A User Guide Controls The Master controls, located on the far right, include reset, system, meters, OVERRIDE, PRESET, and MUTE. A set of buttons appears for each active group. Reset Press the reset button to restore the unit to its default settings. System When multiple Dugan units are linked, groups a, b, and c span linked units and operate as independent automatic mixers. It is possible to have multiple systems of linked units on your network.
Dugan Models E-1 and E-1A User Guide Dugan Control Panel Override Activating the Master OVERRIDE button has the following effect on individual channels: • Channel override button active: puts the channel in man mode with full gain (no automixing); - OR - • Channel override button inactive: mutes the channel. Select channel(s) to include in the override group by activating their override button(s). Remove channel(s) from the override group by deactivating their override button(s).

Dugan Models E-1 and E-1A User Guide Chapter 5: Standalone Hardware Operation The Dugan Control Panel software provides the complete complement of controls for the Model E-1A. However, if for any reason you cannot or do not wish to connect the Dugan Control Panel, you can operate the hardware as a standalone device.
Dugan Models E-1 and E-1A User Guide 4. Set the console faders to your normal operating positions. 5. Balance the preamp gain controls so the fluctuating ambient noise registers equally on the Model E-1A’s meters. Note that raising the preamp gain of one channel causes its gain to rise and the others to fall; it’s a balancing act. When balanced, all mics have equal access to the system gain. 6.
Dugan Models E-1 and E-1A User Guide Standalone Hardware Operation Muting Channels on a Pre-fader Insert The Dugan Speech System works best if inserted post-fader. If your console has only pre-fader inserts, this section describes how to properly mute channels and pre-listen to muted channels. If your console allows post-fader inserts, skip this section. To mute a mic using a pre-fader insert, use the Dugan’s mute buttons. Pulling a console fader down does not properly mute a channel.
Dugan Models E-1 and E-1A User Guide Pre-listening to Muted Channels Using a Post-fader Insert If signal through the Dugan is required to pre-listen to a mic, pull the fader down and put that Dugan channel in bypass mode. When your mic check is done, switch the channel out of bypass and raise the fader so you will be ready to up-cut automatically.
